Volvo XC90

Summary

Mercedes-Benz GLS-Class

If you’re in the market for a full-size, seven-seat, luxury SUV you’re obviously living life large. Big family, lots of friends, dogs and cats, and heaps of activity - horses, boats, camping?

You’re not in the BIG big-buck orbit of the Bentley Bentayga, nor are you ready to plug into the electrified matrix with the Tesla Model X.

You’re aiming at a six-figure bullseye between $130,000 and around $150,000. On a three-year novated lease, somewhere around three grand a month.

Which takes in the chunky Lexus LX and German ‘Big Three’ - the Audi Q7, BMW X7, and this car, the new, third-generation, Mercedes-Benz GLS.

Mercedes-Benz Australia invited us to experience the car on a launch drive across city, suburban and rural roads.

Volvo XC90

Does the Volvo XC90 R-Design T6 have what it takes to match other large seven-seat prestige SUVs... or is it even better?

This Volvo XC90 is where it all began for Volvo way back in 2014. Okay, let me rephrase that, it wasn't the beginning of Volvo – that was in 1927. This second-generation XC90 was a kind of new beginning for Volvo because it brought with it the styling and technology rules for the brand's future models. But how does it hold up now?

See, when the new XC90 arrived in Australia in 2015 it wowed us with its large portrait display, advanced safety equipment and 'Hammer of Thor' headlights. Since then, safety and tech has come along way - has the XC90 been left behind?

And while on the topic of reality checks: what's this large seven-seat SUV like to live with  – how did it cope with our nightmare car park test?

We tested the XC90 R-Design T6. What the heck does that mean? Well the T6 refers to the engine – it's a four-cylinder petrol – and R-Design is the highest trim level.

A four cylinder… in a giant SUV? Yep, we'll get to that.

Verdict

Mercedes-Benz GLS-Class8/10

The new GLS is everything you’d expect of a Mercedes-Benz with an S in its name. Luxury, performance, space, and in this case, thoughtful practicality. A super-capable, super-sized family truckster with the lot.


Volvo XC908.1/10

The XC90 may have been the first of Volvo's new breed of cars, but it remains exceptional in its styling, refinement, technology and safety. The R-Design trim level makes it the burger with almost the lot in that it still gives you room to option more and doesn't assume you want, say a sunroof, when you might not.

The T6 engine is excellent – powerful, with plenty of torque. All that's missing is a beefy soundtrack to go with this brute of an SUV. A cool alternative to a large SUV from BMW, Benz and Audi.

Design

Mercedes-Benz GLS-Class7/10

Launched globally in mid-2019, Merc describes the GLS as the S-Class of SUVs, which is apt given its 5.2m length, 2.5-tonne mass, and ultra-premium specification.

As mentioned, the GLS is big; a step up from the already substantial model it replaces. Built with the US market in mind, in fact it’s produced in Tuscaloosa, Alabama, it’s more than five metres long, close to two metres wide, and over 1.8m tall. And there’s more than three metres between the axles, a 60mm wheelbase increase over the previous model.

And despite the size of the canvas, the Benz design team has managed to make the GLS look like a modern Merc. Signature elements include obvious ones like the slatted grille with a couple of three-pointed stars on the nose.

But there’s also, the carefully chiselled twin ‘power dome’ bonnet, scowling LED headlights and vents to aid front brake cooling and smooth aero performance around the front of the car.

The big beast’s off-road intent is highlighted by extensions around the wheelarches, with big optional 22-inch rims sitting underneath. The fact they look right-sized for the car speaks volumes about its scale.

The racy AMG Line package is standard, and a recess and pronounced character line, tightening the lower waistline is a familiar Merc treatment, plus alloy roof rails toughen the look while dialling up practicality.

The rear is relatively simple, borderline generic, with tapered tail-lights offering the only strong whiff of design personality. But believe it or not, thanks to careful detail sculpting of the body, and smoothing underneath the car it boasts a drag figure of Cd 0.32. Outstanding aero performance for a large SUV.

The driver and front passenger are presented with a sweeping dashboard dominated by twin 12.3-inch digital screens, one primarily covering the instruments, and the central screen managing the MBUX media system, including audio, nav, phone integration, car set-up, and more, plus ‘Hey Mercedes’ voice control.

The overall feel is simple, and restrained, yet massively confident, with a subtle colour palette, large squared-off elements defined by brushed metal finishes, and an obvious, intense attention to detail, from the haptic controls to the beautifully finished, multi-function steering wheel.

And the standard Burmester audio system includes a two-way in-car communication function that subtly amplifies the driver and front passenger’s voices for those in the third row, and vice versa. Sheer genius.


Volvo XC909/10

Can you believe the current Volvo XC90 came into the world in 2014 and still looks this good? Signature elements are the giant grille with its oversized badge, the 'Hammer of Thor' headlights, the unmistakable Volvo tail-lights and the tall profile with enormous windows. Yup, the XC90 is still a futuristic, stylish and elegant-looking brute.

The R-Design trim level enhances the look by adding a gloss-black grille, body-coloured side skirts and bumpers, silver wing mirror caps, aluminium roof rails, a roof-top spoiler, fog lights in the front spoiler, dual tail pipes and the 20-inch alloys you can see in the images.

The modern, minimalist design cabin has also aged well – although the portrait-orientated screen now feels a bit small. I remember writing about how outrageously large it was when it was launched – and then I sat in a Tesla with its mega touchscreen, taking displays to a whole new level.

The R-Design spec makes its presence known in the cabin, too, with the R-Design steering wheel, R-Design Sport pedals and R-Design carpet; it also adds carbon-fibre door inlays and a leather illuminated gearshift knob.

The R-Design trim level also gives buyers two seat trim choices – Nappa leather/Nubuck or Nappa perforated leather. Both are no-cost options and our test car featured the perforated hide.

How big is the XC90? Let's take a look at this seven-seater SUV's dimensions. The XC90 is just less than 5.0m long, more than 2.0m wide (with mirrors) and nearly 1.8m tall.

As far as prestige seven-seat rivals go there's Audi's Q7, Mercedes-Benz's GLS, the Land Rover Discovery and the soon-to-arrive BMW X7.

Practicality

Mercedes-Benz GLS-Class9/10

Space is obviously a critical factor here, and no surprise there’s copious amounts of it inside the GLS.

Front seat passengers enjoy plenty of breathing room, without feeling remote from one another, and there’s lots of storage in the shape of a large lidded box/armrest between the seats, a decent glove box, two big cupholders and jumbo door pockets with room for large bottles.

There’s one data-enabled USB port in the front, two charge-ports in the second row, and four in the third row. Shouldn’t be any complaints about powering mobiles, tablets or games.

The second row feels every millimetre the SUV limo. Simply getting in and out is made easier because an auto lowering function drops the car 25mm when one of the doors is opened.

I was able to sit behind the driver’s seat set for my 183cm position with heaps of head and legroom on offer. And there’s an extra 10cm of electrically adjustable travel to play with if those in the third row agree.

The fold-down centre armrest features a lidded storage tray and twin pop-out cupholders. There are netted pockets on the front seatbacks, and again, the door bins are big enough for large drink bottles.

Three adults across the rear is a breeze, there’s climate control ventilation, and a huge glass sunroof is standard. Rather than asking ‘Are we there yet?’ the kids will be disappointed when you arrive!

Then there’s what the Cleary family refers to as ‘the way back seat.’ A pair of third row seats for the lucky kids that get to inhabit their own little world. Getting in and out is relatively civilised thanks to electric slide and tilt for the second row seats, and space is generous. I could sit comfortably, so the kids will be all smiles.

With all seats upright cargo capacity is enough for a seven-person day trip (355L VDA). Press the button to fold the 50/50 split-fold third row down and your options expand substantially (890L). And with 40/20/40 split-folding second row lowered, transportation of a full, three-ring circus is on the cards (2400L). Overall, more space than the arch enemy BMW X7.

Plus, the ability to lower the car 50mm thanks to the standard air suspension makes life even easier. And one button lowers the second and third rows at the same time.

The spare is a collapsible space-saver, and towing capacity for a braked trailer is 3500kg, with a tow ball weight of up to 140kg. The ESP system also features a trailer stabilisation function that counters oscillation with “braking intervention.”


Volvo XC908/10

It's a giant box on wheels, how could be it be impractical? Actually, there are ways it could be more practical, but first the good points.

There's plenty of room. This is one of the few seven-seat SUVs where even at 191cm tall I can sit behind my driving position with space to spare, and then behind that position in the third row with just enough room for my legs. Headroom in the second row is excellent, but the third row is getting tight although my head still isn't touching the roof.

The doors to the second row are large providing a tall and wide opening for easy entry and exit. The third row is a bit tricky to get into, but I haven't met a single seven-seat SUV where entry into the third-row is a breeze.

Even though the XC90 does well to slide and fold its second row (40/20/40 split) forward, I still ended up crawling in on my hands and knees. Older kids will be able to leap in, so put them back there.

The boot is enormous and with the optional air suspension the XC90 can lower itself like an elephant getting down on its knees to make it easier for you to load stuff into the back. Yup, with all seats up you have 314 litres of boot space; with the third row folded flat you'll have a cargo capacity of 1019 litres, and with all of the seats folded (no not the front ones), there's 1868 litres. Those are measured in ISO litres which are different to the VDA litres used by many other car makers.

Storage throughout the cabin is good but could be better. There are two cupholders in the third row, two in the second and another two up front, and while the storage boxes in the armrests in the third row are an excellent idea, the second row just has small door pockets and seat-back cargo nets. It would be good to see drawers under the seats or even a fold out tray from the centre console.

Storage in the front isn't great either – that long sliding panel next to the shifter (you can see it in the images) houses the cupholders, the glove box is also on the smaller side and so is the storage area under that armrest – but it does contain two USB ports. There's one 12-volt power outlet in the second row, another in the boot and a cigarette lighter (or another 12-volt) in the front.

There's four zone climate control – and directional air vents in all three rows.

Price and features

Mercedes-Benz GLS-Class8/10

The GLS launches in Australia with two models, the turbo-petrol GLS 450 4Matic at $146,500, before on-road costs, and the turbo-diesel GLS 400 d 4Matic at $153,300.

Specification is identical across the two variants, and when you’re competing against the likes of the Lexus LX570, Audi Q7 and BMW X7, as you might expect the list of standard features is lengthy.

Aside from the comprehensive suite of safety tech, covered in the Safety section below, the GLS equipment list includes, 21-inch alloy rims, adaptive high beam assist, air suspension, alloy roof rails, AMG body kit, a huge panoramic sliding glass sunroof, privacy glass from the B-pillar back, auto tailgate, keyless entry and start, rain-sensing wipers, cruise control, LED headlights, and power closing doors.

The power closing doors are a big plus for parents not wanting to disturb kids nodding off in the car, with the soft-touch function drawing the door in for the last few millimetres to an almost silent close.

Inside there’s ambient lighting (64 colours), strategically placed open pore oak wood trim, 13-speaker/590-watt Burmester surround sound audio, electric folding second and third row seats, a head-up display, ‘Mercedes-Benz’ branded illuminated sills, leather seat upholstery (‘Artico’ faux leather on the dash and doors), multi-adjustable electric seats in the front and second row (memory in the front), electrically adjustable steering column, leather-trimmed multi-function steering wheel, and five-zone climate control.

The multi-media system is spectacular, incorporating the twin 12.3-inch digital screens, the central media unit managing nav, digital radio, mobile device connectivity, Apple CarPlay and Android Auto, plus vehicle tracking. There are also remote vehicle status functions (door locking, valet parking, etc), global search (Amazon Alexa, Google Home, Yelp, and Trip Advisor), and a wireless device charging pad.

The basket of goodies can hold its head high in this part of the market, so the value equation stacks up well.

 


Volvo XC908/10

The Volvo XC90 R-Design T6 lists for $104,900, plus on-road costs. The trim level below, with the T6 engine, is the Inscription which lists for $102,900, and the entry-model is the Momentum for $96,900.

So, while nearly $105K might seem like a lot (especially once you add the on-road costs) you can feel comfortable knowing it's actually mighty fine value for money considering the amount of equipment you're given in return.

Coming standard is the 9.0-inch portrait touchscreen and the 12.3-inch digital instrument cluster, a head-up display and sat nav, there's a 10-speaker 330W stereo, Bluetooth and internet connectivity, Apple CarPlay and Android auto, digital radio, 360-degree parking camera, gear shifting paddles, power and heated front seats, four-zone climate control, a pop-out booster child seat in the second row, bending LED headlights, fog lights and a proximity key.


That's along with all the R-Design gear which we covered in the section above and the extensive safety equipment list which we'll cover below.

Our test car was fitted with the $8000 'Premium Package' which brings sunblinds for the rear doors, a Bowers & Wilkins sound system, air suspension, plus tailored dashboard and door trims. The 'Bursting Blue' metallic paint our car wore is a $1900 option.

Worried you're paying too much? Fear not, because relative to most other prestige seven-seat SUVs the XC90 R-Design T6 is at the more affordable end of the pricing spectrum.

Audi's Q7 3.0TDI Quattro lists for $106,900, Mercedes-Benz's GLS 350d is $118,729, while the Land Rover Discovery TD6 HSE manages to undercut it at $103,000.

It's interesting to note that while the XC90 T6 has a petrol engine, those rivals are diesels. Audi doesn't make a petrol Q7, Land Rover does make petrol Discoveries but only sell diesel ones in Australia, and as for a Benz GLS petrol there's only one - the GLS 500 and that lists for $165,129, which is $60K higher than our Volvo XC90. 

Engine & trans

Mercedes-Benz GLS-Class8/10

There are two engines on offer. The 3.0-litre (M256) in-line six-cylinder turbo-petrol GLS 450 4Matic, and the 2.9-litre (OM656) in-line six-cylinder turbo-diesel GLS 400 d 4Matic.

The all-alloy, twin-scroll single-turbo petrol engine delivers peak power of 270kW from 5500-6100rpm, and maximum torque of 500Nm across a broad plateau from 1600-4500rpm. It also features a 48-volt electrical system driving the ‘EQ Boost’ set-up, able to deliver an extra 16kW/250Nm for short periods. The integrated starter-generator also enables energy recuperation.

Although the all-alloy, twin-turbo diesel features variable valve lift it gives some ground on power, offering up 243kW between 3600-4000rpm, but torque is a solid whack, with 700Nm on tap from 1200-3000rpm. Worth noting, that to minimise emissions this engine features a “selective catalytic reduction converter” in the exhaust, which brings with it the use of an ‘AdBlue’ reducing agent. The separate AdBlue tank has a capacity of 31.6 litres.

The nine-speed auto transmission is the same in both versions, although the diesel has a slightly lower final drive ratio.


Volvo XC908/10

The T6 in XC90 R-Design T6 refers to the engine – a 2.0-litre four-cylinder supercharged and turbocharged petrol.

You may have noticed in the images that our test car wears a tiny blue square on its tailgate. This is the badge of Volvo's Polestar performance tuning division. All R-Design XC90s come with the 'Polestar Optimisation' package which increases the T6's power output from 235kW to 246kW and its torque from 400Nm to 440Nm.

The Polestar Optimisation package also recalibrates the XC90's throttle response and increases the shifting speed of the eight-speed automatic.

Acceleration from 0-100km/h according to Volvo is 6.4 seconds which is a tenth of a second quicker than an 'un-Polestar-optimised' T6 - say in the Inscription T6 or Momentum T6.

The XC90 R-Design T6 is all-wheel drive and for the five of you out there who will ask, including my father in-law – it's a Haldex 'Generation 5' system.

My bet is the same people will also want to know its braked towing capacity: 2400kg.

Fuel consumption

Mercedes-Benz GLS-Class8/10

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle for the GLS 450 is 9.2L/100km, the more frugal GLS 400 d trimming that to 7.7L/100km. The petrol 450 emits 210g/km of CO2 in the process, the diesel 400d dropping that slightly to 202g/km.

Stop-start is standard, you’re looking at premium unleaded for the 450 GLS, and you’ll need 90 litres of dinosaur juice to full the tank on both models.

 


Volvo XC908/10

Volvo says the T6 four-cylinder turbo- and supercharged petrol engine with its eight-speed auto should use 8.5L/100km over a combination of open and urban roads – this goes for the Polestar Optimised T6, too.

We measured our test car's fuel economy at the petrol pump and calculated that after 246km of mainly suburban and city running we were using 14.3L/100km. The trip computer reported a slightly higher figure of 14.5L/100km.

Driving

Mercedes-Benz GLS-Class7/10

Merc claims the GLS 450 will sprint from 0-100km/h in 6.2sec, and the 400 d in 6.3sec. Not hanging around for a 2.5 tonne mothership. But the standout is the 400 d’s torque. All 700Nm of it available from just 1200rpm to 3000rpm; right in the mid-range sweet spot.

The nine-speed auto transmission is smooth yet responsive, with paddles on the wheel for manual shifts when you want to pick the ratio. The combination of effortless grunt and the nine-speeder keeping things on the boil is an impressive one.

Suspension is by double wishbones at the front and multi-links at the rear, and while you can feel the weight in cornering, the standard Airmatic air suspension (which does away with steel springs) is superb in terms of ride comfort and body control.

We took a deep breath and pushed enthusiastically through a series of sweeping corners and the fat (285/45 fr - 325/40 rr) Continental ‘PremiumContact 6’ rubber wrapped around our car’s (optional) 22-inch rims gripped hard.

The ‘4Matic’ all-wheel drive system also seamlessly shuffles torque between the front and rear axles (theoretically up to 100 per cent in each direction).

Merc has put extra focus on body rigidity, the tuning of engine and suspension mounts, and sound absorption, and it shows. The GLS 400 d is beautifully refined on the highway. A neat touch is the car automatically lowering 15mm at motorway speeds or when ‘Sport’ mode is selected.

Steering is electromechanically assisted, and Merc says the front suspension geometry has been revised to minimise vibration through the wheel. And yes, feedback is minimal, but unfortunately so is road feel with only a general connection between your hands on the wheel and the front tyres on the bitumen.

When you’re steering a large beast like this, often with something substantial hitched to the back, you want to know braking performance is up to the task, and the GLS’s big ventilated discs all around deliver reassuringly strong stopping power, with nice, progressive pedal feel to boot.

The seats are adjustable six ways to Sunday, but beyond that they’re comfortable and supportive, even over long stints behind the wheel.

We stayed on the bitumen, because, let’s face it, that’s where this car will spend 99.9 per cent of its time, with the exceptions of the boat ramp, a ski weekend or pony club.

For those special occasions the optional ‘Off-road engineering package’ adds a low-range transfer case, inter-axle locking, hill descent control, and under body armour for more serious work.


Volvo XC908/10

At 5.0m long, 2.0m wide and nearly 1.8m tall the XC90 R-Design T6 is big, but in comparison to other large SUVs it's one of the easiest to drive.

The images in this review were taken at the top of an eight-storey carpark: it's a good place to take photos of my review cars and at the same time test pilot them through probably the worst-designed car park you'll encounter.

Narrow ramps and tight turns are not really ideal conditions for a large SUV but the great visibility through the XC90's big windows, the excellent field of vision offered by the wing mirrors, the light steering and smooth throttle response made climbing to the summit pretty simple.

The flat, broad bonnet helps with being able to see exactly how much room you have between the concrete pylon and an insurance claim, too. Other large SUVs with curvaceous lines and noses that dip away from sight will have you sitting up like a meerkat trying to see how much room you have.

A four-cylinder petrol engine may seem small for such a large SUV but the T6 is outstanding – it's efficient and impressively powerful. Not once did I feel like it was lacking in grunt, but there were many times I wished the exhaust note sounded beefier.

Our car had the optional air suspension which for the most part turned out a composed and comfortable ride, although being fitted with fairly low profile tyres on large wheels (Continental ContiSport Contact5 275/45 R20) meant when the road surface turned bad the ride suffered.

And these aren't even the largest wheels. The R-Design T6 comes with no-cost option 22-inch wheels – they look good, but you'd be wise to try them before you buy.

The touchscreen will take some getting used to – I kept discovering more hidden 'pages' and functions the more I swiped around it.

A serenely quiet cabin, comfortable seats with uber-stylish surrounds, a commanding driving position and not being in just another German SUV made the experience even more special.

Safety

Mercedes-Benz GLS-Class10/10

At the time of this launch drive the GLS hadn’t been safety assessed by ANCAP, but you could make a small wager, like every penny you have to your name, that it will score a maximum five stars.

The expected active features are there, including ABS, ASR, and ESP, with additional tech including ‘Active Blind-Spot Assist’, ‘Active Brake Assist' (Merc-speak for AEB), active lane keeping and lane change assist, ‘Adaptive Brake’, ‘Attention Assist’, ‘Evasive Steering Assist’, ‘Parktronic’ (active parking assist with 360-degre camera), rear cross-traffic alert, traffic sign assist, and a tyre pressure warning system.

Then, if all that isn’t enough to avoid an impact the GLS is equipped with nine airbags (front and pelvis side for driver and front passenger, side for outer rear seat occupants, full-length curtain, and a driver’s knee bag), an active bonnet to minimise pedestrian injuries, and the ‘Pre-Safe Plus’ (flashes rear hazards to warn drivers closing too quickly from behind, tightening the belts at the same time, and locking the brakes if the GLS is stationary with a rear impact imminent).


Volvo XC909/10

If this was Family Feud and the question was: 'Name a type of car that's safe? I'd bet the answer would be 'Volvo' every time. I'd also wonder if Volvo had paid for the question to be asked on the show.

Anyway, the reputation is justified and the brand continues to pioneer life-saving technology and equip its cars with the latest safety gear.

What's just as noble is how Volvo applies the full range of safety systems to all grades of XC90 – so even the base grade Momentum T6 comes with the same safety features as the R-Design T6.

This includes AEB which Volvo says is active from four km/h and can brake effectively to avoid a collision with a pedestrian at up to 45km/h. At speeds higher than 45km/h but below 70km/h the collision is mitigated.

According to Volvo the system will also detect cyclists and if one swerves into the path of the car, the XC 90 can reduced its speed by up to 50km/h. As for other cars, the XC90 can brake to avoid a collision if the speed difference between the cars is less than 30km/h.

The XC90 is also equipped with adaptive cruise control with stop and go function, lane keeping assistance, blind spot warning, rear cross traffic alert with AEB that works while reversing.

A run-off mitigation feature also brakes and uses evasive steering to pull the car back into its lane if the vehicle accidentally starts to veer off the road.

The XC90 is fitted with front airbags, side airbags, driver knee airbag, plus second and third row inflatable curtains.

For child and baby seats you'll find two ISOFIX mounts and three top tether points across the second row – there aren't any in the third row.

The XC90 R-Design T6 has a space saver spare located under the boot floor.

Chinese company Geely own Volvo, but the XC90s that are sold in Australia are made in Sweden.

Ownership

Mercedes-Benz GLS-Class7/10

The Mercedes-Benz range is covered by a three year/unlimited km warranty, which, like Audi and BMW continues to lag behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.

On the upside, Mercedes-Benz ‘Road Care’ roadside assistance is included in the deal for three years.

Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.

As a guide, service pricing for the outgoing GLS is set at $2600 per service (up-front) and $3250 (PAYG), a saving of $650 a pop. Fourth and fifth services are also available for pre-purchase ($3550 and $4900).


Volvo XC907/10

The XC90 is covered by Volvo's three-year/unlimited kilometre warranty. Servicing is recommended every 15,000km or 12months – whichever comes first.

There are two service programs offered for the XC90. There's the 'SmartCare' plan which costs $2225 for three years/45,000km; $3500 for four years/60,000km and $4230 for five years/75,000km. Then there's the 'SmartCare Plus' plan which costs $3050 for three years/45,000km; $5350 for four years/60,000km and $6540 for five years/75,000km.

It would be good to see Volvo offer capped price servicing, which doesn't need to be purchased as an additional piece of coverage.
